Adjustable crayon holder



m wz March 24, 1931. J. P. NICHOLAS ADJUSTABLE CRAYON HOLDER Filed June12, 1929 ATTORNEY Patented Mar. 24, 1931 UNITED STATES JOHN P. NICHOLAS,F ENUMCLAW, WASHINGTQN ADJUSTABLE CRAY ON HOLDER Application filedZl'une 12,

This invention relates to writing, marking or drawing devices and hasfor its object the provision of a novel crayon holder of suchconstruction as to permit a crayon, chalk or I the like to be securelyheld at a desired posi tion so that more or less may be exposed forservice.

An important object of the invention is to provide a holder of thischaracter having novel adjustable means for varying the pressure uponthe crayon or chalk held in it so that slippage will be positivelyprevented while at the same time there will be no danger of crushing orbreaking the crayon.

Another object of the invention is to provide a device of this characterembodying spring means normally tending to urge the crayon into extendedor projected position so that it will be exposed for service, meansbeing also provided for adjusting the spring tension upon the crayon deending upon cir 'cumstances or how far it lias become worn down.

An additional object is to provide a device of this character which willbe simple and inexpensive to make, easy to use, positive in action,efiicient and durable in service, and a general improvement in the art.

With the above and other objects and advantages in view, the inventionpreferably consists in the details of construction and the arrangementand combination of parts to be hereinafter more fully described andclaimed, and illustrated in, the accompanying drawin, in which igure 1is a side elevation of the complete device.

Figure 2 is a longitudinal sectional view taken substantially on theline 2-2 of Figure 1. 1

Figure 3 is an end elevation.

Figure 4 is a cross section taken on line 4-4 of Figure 1.

Figure 5 is an elevation of the opposite end. Referring moreparticularly to the draw ing, I have shown the device as comprising anelongated hollow or tubular body which is here represented as hexagonalin cross section though it should be distinctly understood that theremight be fewer or more fiat faces if the 1929. Serial No. 370,370.

such is'desired for any reason. At one end this body 10 is slightlyenlarged as indicated at 11, tapered ofi as shown, threaded as at 12 andsplit or slotted asindi'cated at 13, an adjusting nut 14 being screwedonto the thread ed portion 12. Throughout the major portion of itslength the body or tubular member 10 is represented as having its anglethreaded as indicated at 15 for engagement thereon of a nut member 16which abuts against aslidable sleeve 17 corresponding in cross sectionto the cross section of the tubular body 10. Furthermore, the majorportion of the body is formed with-elongated slots 18 through whichpasses a pin or the like 19 which engages against and constitutes anabutment for one end of acoil spring 20.

. In the use of the device, the crayon indicated at B is inserted throuh the open end of the tubular body or mem er 10, it being of coursenecessary at this time that the nut 14 be unscrewed to substantially itsmaximum extent.

The crayon B is pushed down or into the body 10 until it engages againstthe spring I 20 and may be additionally pushed to compress the spring sothat only the desired amount of the crayon will project beyond the openend of the tubular body. The desired position having been obtained, theoperator grasps-the nut 14 and turns it in a clockwise direction so asto screw it onto the tapered threaded portion 12 of the enlarged end 11of the body and it is then quite evident that the travel of this nutalong the tapered portion will contract this end of the tubular ody, theslits or slots 13 permitting the action, so that a thorough clampingaction upon the crayon will be obtained.

In order to get more crayon out of the 99 holder for use it is notnecessary to screw down on nut for the first time as inside spring istight enough in holding crayon, but in the second time unloosen nut 14for more crayon. Then screw nut 14 tight, then screw nut 16 down soinside spring is held tight against crayon. It should also be noted thatcrayon can be used up to one-quarter inch in length.

In the operation, the device is used in exactly the same manner as anyother for the same purpose but the feature of novelty and advantageresides in the provision of the clamping nut members and the adjustingnut means together with the spring coact ing with the crayon so that thecrayon may be projected more and more during the use of the device sothat it is entirely consumed, there being consequently no waste.

From the foregoing description and a study of the drawing it is believedthat'the cons'truction, operation and advantages will be readilyunderstood without further explanatory matter.

While I have shown and described the preferred embodiment of theinvention, it should be understood that I reserve the right to make allsuch changes in the details of construction and the arrangement andcombination of parts as will not depart from the a spirit of theinvention or the scope of the subjoined claim.

Having thus described the invention, I claim A crayon holder comprisingan elongated tubular body open at one end and closed at the other andadapted to contain a crayon, means at the open end of the body for contracting the same to clamp the crayon and restrain it against movement,said body being exteriorly threaded and formed with diametricallyopposite longitudinally extending slots, a sleeve slidable externallyupon the body, a transverse pin passing through the sleeve and saidslots, a spring located Within the body and having one end abuttingagainst the crayon and its other end against said pin for normallyurging the crayon outwardly, and a nut threaded onto the body inabutting engagement with the sleeve for moving the same to vary thespring pressure against the crayon whereby upon release of said clampingmeans the crayon will be projected.

In testimony whereof I affix my signature.

JOHN P. NICHOLAS.
